My Mid-2009 Macbook Pro running Yosemite gave me a B-tree invalid node size error last week after it got stuck waking up from sleep mode, forcing me to do a hard shutdown.
I have done Time Machine backups; problem being the last one is from a month ago. In between, I have some important files I need to recover. If I restore the April 13th backup, will it overwrite the updated files (presumably)? Will it wipe out new files that didn't exist a month ago?
I did have a copy of Disk Warrior 4.1; it made it through 5 steps and failed with a message like "the file system is newer than expected and rebuilding the directory could result in data loss" or something like that. I ran it twice, same fail error. Would upgrading to the latest Disk Warrior solve the problem? This was running my problem disk in a USB enclosure off from a 2006 Macbook running a much older version of OSX (maybe 10.4 or 10.5).
I don't want to do anything to destroy my data, but I needed a computer to keep operations running, so I bought a new Macbook Pro Retina 13" 256GB. Disk Warrior 4.1 will not run on that machine for some reason (looking for a Prefs file I don't have).
Is there anything I can do cheaply to retrieve in particular 2 files which contain financial transactions? (Lesson learned to back up more frequently than monthly).
Thanks
